摘要
试验比较了两组砂浆在标准养护和自然养护条件下的长期强度,结果表明固硫灰干混砂浆在任何龄期下都能超出对照组,并且自然养护高于标准养护,受限条件高于非受限条件;在各种侵蚀性介质中,固硫灰干混砂浆对淡水、稀酸和硫酸盐具有较好的抵抗能力,而稀碱和氯盐则影响其长期强度的增长,这均源于固硫灰自身组成与结构,是其对砂浆内养护的结果。
Compared the long-term strength of the two groups of dry mixed mortar under standard curing and natural curing,the re sults show that the CFBC in dry-mixed mortar could exceed the control group under any ages,and the natural curing was higher than the standard curing,the restricted condition was higher than the unrestricted condition.In a variety of corrosive media,the sulfur-fix ing ash dry mixed mortar has a good resistance to fresh water,dilute acid and sulfate,while affect the long-term strength growth in the dilute alkali and chloride,which is due to the composition and structure of CFBC itself,is the result of its autogenously curing in mortar.
